Abstract

A method is disclosed that is performed by a first network node in communication with a second network node. The second network node has been requested or is being requested to send measurements and/or predictions available at the second network node to the first network node. The method comprises receiving, from the second network node, a first message comprising a first indication that sending of measurements and/or predictions from the second network node to the first network node is to be paused, delayed, resumed, or stopped. Also disclosed are a method performed by a second network node, and first and second network nodes.
